The OP went from a 5W-40 to a 5W-30 and oil use didn't drop?
What am I missing?
I would think that ST is available in 40 weight, and certainly Rotella is cheaper
than VML.

Yeah, Kirkland oil is essentially the same thing and can be had for even less if you’re a member… As my stash dwindles, I’m slowly replacing with the Kirkland 5w-30 and 0w-20

Valvoline HM Full Synthetic is a thin oil for its grade. I've experienced low oil pressure with it too at idle in a worn engine that burns some oil. Ironically, I'm running it in two vehicles now, but they're both spec'd for a 20 and I'm using 5W30 since I wanted a bit thicker.
